While I agree Yut, it's only concept art, so the game could be very different from that. That being said,

AP: Bungie seems to be cooking up something amazing and I cannot wait to play the hell out of whatever they release next.

Bungie has never done me wrong. And yeah, while it could be different from what is seen there, it gives us a good idea.Also: "Our story begins seven hundred years from now in the Last City on Earth, in a Solar System littered with the ruins of man's Golden Age. A massive, mysterious alien ship hangs overhead like a second Moon. No one knows where it came from or what itís here for, but only that itís our protector. Meanwhile, strange, alien monsters creep in from the edge of the universe, determined to take Earth and the Last City. We are young 'knights' tasked with defending the remains of humanity, discovering the source of these monsters and -- eventually -- overcoming it."
